    Holding Tank, specifically in a CHB 34' twin cabin

    Easily done, Peggie, and mostly my fault - there is more than one Campbeltown in the world, so I've amended my profile to add "Scotland". I'm always very grateful for your expert input, no matter where I am!

    Holding Tank, specifically in a CHB 34' twin cabin

    Thank you for your kind response. GRP can either be polyester based (if it has a gelcoat, it's polyester) or epoxy. Polyester sticks to polyester, but not to epxoy. Epoxy seems to stick to virtually anything. I don't think Ronco have a Scottish branch, but I fitted a UK made Tek Tanks custom...

    Holding Tank, specifically in a CHB 34' twin cabin

    Yes, if I get a rope on the after end or a piece of timber under the forward end, I can move it up and down by around an inch, just! Hopefully once it starts, it might ease a little. This is going to involve moving pipes, bilge pumps and part of the bulkhead to get access, so I'll leave it until...

    Holding Tank, specifically in a CHB 34' twin cabin

    My black water tank is definitely GRP (polyester?). Further investigation reveals that all of the inlets, outlets and breather pipes (all on the aft face of the tank) are, or were, steel. I say were because, unsurprisingly, some of them have rusted away almost completely. Also, the tank is not...

    Holding Tank, specifically in a CHB 34' twin cabin

    Thank you very much for your advice, Peggie. All relevant and, however I do the job, I will make sure it's all replaced and maintainable! One query which I hadn't thought of before. The longer runs of what remains of the old black water plumbing have been done in what looks like standard rigid...

    Sounds like an option!

    Holding Tank, specifically in a CHB 34' twin cabin

    Thank you for your replies The tank that I have was built in by the boatbuilders - it is under the parquet flooring in the forecabin, which has obviously never been touched since. So I can't measure the volume as the floor is fixed and I don't know how far it extends. Unfortunately I can't fit...

    Holding Tank, specifically in a CHB 34' twin cabin

    Hi I finally managed to open the (stuck fast) small hatch under the steps down to the forward cabin to discover that there seems to be a holding tank down there. I was looking at fitting a holding tank anyway, so this was a very welcome surprise... perhaps! But it seems to have been blocked...

    Asbestos?

    Thank you to everyone for your comments and advice. I sent a sample off for testing and have just received the results - "No Asbestos Detected in Sample". Phew! But well worth the expenditure for peace of mind.

    Asbestos?

    Get it tested... that sounds like excellent advice. Thank you sunchaser and C electric, that is what I shall do. I'll post the results when I have them.

    Asbestos?

    Our (new to us) 1978 CHB Puget Sound 34 has white fibrous tiles under the sole over the engines. I don't know if these were original equipment or if they were added later. Has anyone else come across these and, the big question, does anyone know if they contain asbestos... or not?

    Helm pump, pumping air?

    Helm pump, pumping air?

    Thank you. My overall conclusion is that there is an air leak by the old upper helm , plus air in the system somewhere and probably quite a lot. But what is happening when I turn the wheel is that air is TEMPORARILY being pulled into the reservoir and as soon as I stop turning, it is then...
